Double jeopardy is a procedural defence that prevents an accused person from being tried again on the same charges following an acquittal and in rare cases prosecutorial and/or judge misconduct in the same jurisdiction. A variation in civil law countries is the peremptory plea, which may take the specific forms of autrefois acquit or autrefois convict. These doctrines appear to have originated in ancient Roman law, in the broader principle non bis in idem.
A felony is traditionally considered a crime of high seriousness, whereas a misdemeanor is regarded as less serious. The term "felony" originated from English common law to describe an offense that resulted in the confiscation of a convicted person's land and goods, to which additional punishments including capital punishment could be added; other crimes were called misdemeanors. Following conviction of a felony in a court of law, a person may be described as a felon or a convicted felon.
A misdemeanor is any "lesser" criminal act in some common law legal systems. Misdemeanors are generally punished less severely than more serious felonies, but theoretically more so than administrative infractions and regulatory offences. Typically misdemeanors are punished with monetary fines or community service.
A summary offence or petty offence is a violation in some common law jurisdictions that can be proceeded against summarily, without the right to a jury trial and/or indictment. In the law of the United States, petty offences are typically those that carry the lightest maximum penalty.
The Sixth Amendment to the United States Constitution sets forth rights related to criminal prosecutions. It was ratified in 1791 as part of the United States Bill of Rights. The Supreme Court has applied the protections of this amendment to the states through the Due Process Clause of the Fourteenth Amendment.
In criminal law, the intoxication defense is a defense by which a defendant may claim diminished responsibility on the basis of substance intoxication. Where a crime requires a certain mental state to break the law, those under the influence of an intoxicating substance may be considered to have reduced liability for their actions. With regard to punishment, intoxication may be a mitigating factor that decreases a prison or jail sentence. Numerous factors affect the applicability of the defense.
Attempted murder is a crime of attempt in various jurisdictions.
Beyond a reasonable doubt is a legal standard of proof required to validate a criminal conviction in most adversarial legal systems. It is a higher standard of proof than the balance of probabilities and is usually therefore reserved for criminal matters where what is at stake is considered more serious and therefore deserving of a higher threshold.
An attempt to commit a crime occurs if a criminal has an intent to commit a crime and takes a substantial step toward completing the crime, but for reasons not intended by the criminal, the final resulting crime does not occur. Attempt to commit a particular crime is a crime, usually considered to be of the same or lesser gravity as the particular crime attempted. Attempt is a type of inchoate crime, a crime that is not fully developed. The crime of attempt has two elements, intent and some conduct toward completion of the crime.
In France, a cour d'assises, or Assize Court, is a criminal trial court with original and appellate limited jurisdiction to hear cases involving defendants accused of felonies, meaning crimes as defined in French. It is the only French court consisting in a jury trial.
Sparf v. United States, 156 U.S. 51 (1895), or Sparf and Hansen v. United States, was a United States Supreme Court case testing the admissibility of confessions by multiple defendants accused of the same crime, and the responsibility of juries.
Manslaughter is a common law legal term for homicide considered by law as less culpable than murder. The distinction between murder and manslaughter is sometimes said to have first been made by the ancient Athenian lawmaker Draco in the 7th century BC.
Taylor v. United States, 495 U.S. 575 (1990), was a U.S. Supreme Court decision that filled in an important gap in the federal criminal law of sentencing. The federal criminal code does not contain a definition of many crimes, including burglary, the crime at issue in this case. Yet sentencing enhancements applicable to federal crimes allow for the enhancement of a defendant's sentence if he has been convicted of prior felonies. The Court addressed in this case how "burglary" should be defined for purposes of such sentencing enhancements when the federal criminal code contained no definition of "burglary." The approach the Court adopted in this case has guided the lower federal courts in interpreting other provisions of the criminal code that also refer to generic crimes not otherwise defined in federal law.
James v. United States, 550 U.S. 192 (2007), is a decision by the Supreme Court of the United States that held that attempted burglary could serve as a predicate felony under the federal Armed Career Criminal Act (ACCA), which provided that a person convicted of being a felon in possession of a firearm with three prior convictions for either serious drug offenses or violent felonies must be sentenced to a mandatory minimum 15-year prison term.
The Double Jeopardy Clause of the Fifth Amendment to the United States Constitution provides: "[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb..." The four essential protections included are prohibitions against, for the same offense:
The Armed Career Criminal Act of 1984 (ACCA) is a United States federal law that provides sentence enhancements for felons who commit crimes with firearms if they are convicted of certain crimes three or more times.
Aiding and abetting is a legal doctrine related to the guilt of someone who aids or abets another person in the commission of a crime. It exists in a number of different countries and generally allows a court to pronounce someone guilty for aiding and abetting in a crime even if they are not the principal offender. The words aiding, abetting and accessory are closely used but have differences. While aiding means providing support or assistance to someone, committing a crime in exchange of a commission or compensation, abetting means encouraging someone else to commit a crime. Accessory is someone who in fact assists "commission of a crime committed primarily by someone else".
Responsibility for criminal law and criminal justice in the United States is shared between the states and the federal government.
Capital punishment is a legal penalty in the U.S. state of North Carolina.
Schmuck v. United States, 489 U.S. 705 (1989), is a United States Supreme Court decision on criminal law and procedure. By a 5–4 margin it upheld the mail fraud conviction of an Illinois man and resolved a conflict among the appellate circuits over which test to use to determine if a defendant was entitled to a jury instruction allowing conviction on a lesser included charge. Justice Harry Blackmun wrote for the majority; Antonin Scalia for the dissent.
